Metal-Organic Frameworks: The Material Revolution That Could Save Our Planet
Context from today’s quiz: The 2025 Nobel Prize in Chemistry was awarded to Susumu Kitagawa, Richard Robson, and Omar M. Yaghi for their pioneering work on Metal-Organic Frameworks (MOFs). These crystalline materials have extraordinarily large surface areas and can be customized for gas capture, chemical storage, catalysis, and even harvesting water from desert air.
🤔 Your Perspective Matters
MOFs represent a paradigm shift in materials science. A single gram of MOF can have a surface area equivalent to a football field! This makes them incredibly effective for capturing carbon dioxide from the atmosphere, storing hydrogen for clean energy, purifying water, and even delivering drugs precisely within the body.
How can India leverage MOF technology to address its pressing challenges in carbon capture, water scarcity, and clean energy storage?
How can India leverage MOF technology to address its pressing challenges in carbon capture, water scarcity, and clean energy storage?
- Could MOF-based carbon capture be the key to India meeting its 2070 net-zero commitment while continuing industrial growth?
- How might water-harvesting MOFs transform life in India’s water-scarce regions like Rajasthan and Bundelkhand?
- What investments should India make in MOF research to become a global leader in this transformative technology?
